CNC engraving and milling machine CNC system of the linear interpolation and circular interpolation are the two most important interpolation, many complex curve can be fitting by these two kinds of interpolation, according to the digital integrator (
DDA)
The principle can write these two kinds of the realization of interpolation arithmetic functions.
Figure 1, figure 2 is the client software in CNC engraving and milling machine host layer to realize their flow chart.
figure 1 DDA numerical control system linear interpolation process
figure 2 DDA numerical control system of arc interpolation process
for other types of interpolation, the thinking of implementation is similar to the above two, all need according to CNC engraving and milling machine> CNC system principle and algorithms of interpolation for every little bits of incremental interpolation process, the increment of stepper motor is a basic action, the basic action sequences, in turn, sent to the SCM tool can be realized at the bottom of the interpolation motion.
engraving machine price information in the numerical control network.
